We look at the division of 834435 by 20 
The aim is to understand the frequency of 20 in 834435.

Moving on to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Advancing to step 2:
20 can be fit into 83 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 80 from 83, we get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 20

Step 3:
If we divide 34 by 20, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 41.0
Deduct 20 from 34 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 20

Moving on to step 4:
20 can be fit into 144 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 417.0
The remainder is 4 after subtracting 140 from 144.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 20

Moving on to step 5:
43 divided by 20 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 4172.0
Subtract 40 from 43 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 20

Going ahead to step 6:
The number 20 fits into 35 1 times, leaving a remainder of 15.
The next digit of our result is 1. 
Result so far: 41721.0
If we take 20 away from 35, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 20, we get 7 and a remainder of 10.
The next digit of our result is 7. 
Result so far: 41721.7
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 41721.75
Subtract 100 from 100 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 41721.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 41721.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 41721.75, and the remainder is 0.0.
